MegaMIMO 2.0 Is The Faster Wi-Fi We All Need

There always seems to be a speed issue when accessing a wireless network in a public place. But thanks to research from MIT, you may soon say goodbye to slow coffeehouse Wi-Fi. Researchers from MIT's Computer Science and Artificial Intelligence Lab (CSAIL) have developed MegaMIMO 2.0, a Wi-Fi system that is three times faster than traditional Wi-Fi and has double the range.

Wi-Fi speeds are slow in public places due to interference. If a lot of people are trying to connect to the same internet connection, the speed practically slows to a halt because there isn't enough wireless spectrum available for people to get their data quickly. MegaMIMO 2.0 is designed to juggle multiple access points at once without creating interference. It does this all while remaining on the same frequency. Get more details on this Wi-Fi system, and learn more about Wi-Fi in general, with the videos below.

How Does Wi-Fi Work?

You can't see it, but it's there.

Key Facts In This Video

  1. Ethernet allows data to be converted into an electrical signal carried by a wire. The data is carried through radio waves when using Wi-Fi. 00:37

  2. To avoid interference, Wi-Fi signals are transmitted at one of two frequencies, 2.4 GHz or 5.0 GHz. 01:02

  3. TCP/IP is the protocol in which an image is broken down into smaller packets, directed into the receiving router and reassembled to form the image. 01:17

Is Public Wi-Fi Dangerous?

It's slow, that's for sure.

Key Facts In This Video

  1. In 2011, the United Nations declared internet access to be a human right. 00:54

  2. Dark Hotel is a group of elite hackers widely considered to be under the command of a government who exploit executives on hotel WiFi. 02:02

  3. The next time you're in a public place, carefully consider how free that WiFi really is. 03:21
